Huh. I use 4.5yo to round to four-and-a-half years old. I never take the time to count the months. I think I stopped that about the time DS4.5 hit 2yo because it was too much effort and I'm too lazy! wink

The lone exception is if we're talking about test-taking month, when specific month of age matters (and then I write it as 4y3m or whatever). Otherwise, I only work in half-year increments. I wouldn't ever write 4.3, only 4 or 4.5.

FWIW...
